The word(s) "doubted" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.

(2) Is there disease in their hearts? Or have they doubted? Or do they fear that Allah will be unjust to them, or His Messenger? Rather, it is they who are the wrongdoers.

(3) The hypocrites will call to the believers, "Were we not with you?" They will say, "Yes, but you afflicted yourselves and awaited [misfortune for us] and doubted, and wishful thinking deluded you until there came the command of Allah. And the Deceiver deceived you concerning Allah.
